Horizen EON Explorer

The Horizen EON Explorer leverages the feature-rich Blockscout Explorer, an online tool for inspecting and analyzing the Horizen EON blockchain. Blockscout is open-source code that allows the ability to customize a block explorer instance to view all transactions, past and current, on the blockchain. Customization options include information such as the network's hash rate and transaction details.

Note: Use Search to query for a specific transaction, address (wallet or contract), block, and token.

Key Features​

The key features of the Horizen EON Block Explorer are modularized in each of the panels in the main landing page.

Daily Transactions​

The Daily Transactions dashboard provides a real-time view of the blockchain with various data points.

  • A graph view of transactions processed during a time period. It includes metrics for tracking gas and transactions on a daily basis.
  • Total blocks - The total number of blocks in the blockchain.
  • Average block time - This is the average time that a block is created.
  • Total transactions - The total number of transactions in a time period in the blockchain.
  • Wallet address - The total number of wallet addresses associated with transactions in the blockchain.

  • Number of transactions - The running number of transactions for the block.
  • Elapsed timer for the block - A timer that displays the elapsed time since the block creation.
  • Forger (wallet) address - The miner’s address. Click the miner's address link to navigate to the Address Detail page.

Latest transactions​

The Latest transaction module provides key information about the latest transaction.

transactions

Key information includes:

  • Transaction ID (hash) - The unique identifier that validates the transaction.
  • Type - The specific type of the transaction (Coin transfer, Contract call, etc.).
  • Transaction Status - Indicates the status (Success or Error) details of the transaction.
  • (Sending) Address - The sending address of the transaction. Click the address receiving asset link navigate to the to Address Detail page.

Block Explorer Features​

The EON Block Explorer gives you the ability to search the blockchain for transactions, addresses, and statistics, including the customized features of:

  • Backward Transfer
  • Forward Transfer
  • Fee Payment

Typically, when a user decides to move ZEN from a sidechain back to the mainchain (to either send ZEN to another sidechain or to cash out, for example) the backward transfer transaction is deployed. Backward transfers are initiated on EON (EVM sidechain) as special transactions batched in withdrawal certificates and propagated by EON nodes to the mainchain.

The EON Block Explorer highlights the Backward Transfer transaction:

backward-transaction

Key information includes:

  • Txn hash - The unique identifier that validates the transaction.
  • Method - In the case of backward transfers the method is always backwardTransfer.
  • From - The sending address of the transaction.
  • To - In the case of backward transfers the destination address is the Withdrawal Request native contract.
  • Value tZEN - The amount of TZEN transferred in the transaction.
  • Fee tZEN - The TZEN amount charged to process the transaction.

Forward Transfer​

When a user requests for TZEN from the Horizen Faucet, the forward transfer transaction is initiated. A forward transfer moves assets from the mainchain to the sidechain. These transactions, more specifically the transaction outputs, are unspendable on the mainchain. However, they include some metadata so they are redeemable on EON.

It is the responsibility of EON nodes to monitor the mainchain for incoming transactions, and include them in EON.

The EON Block Explorer lists the Forward Transfer transaction:

forward-transaction

Key information includes:

  • Block - The number assigned to the block.
  • Elapsed timer for the block - A timer that displays the elapsed time since the block creation.
  • To - The recipient address of the forward transfer.
  • Value tZEN - The amount of TZEN transferred in the forward transfer.

Fee Payment​

The blockchain fee is a ZEN-denoted fee that users are charged when processing transactions. The fee is required to process the transaction on Horizen EON and ensures that transfers arrive at their expected destination. The fees are aggregated and paid to forger nodes that have forged at least one block during the last withdrawal epoch.

The EON Block Explorer lists the Fee Payment transactions:

fee-payment

Key information includes:

  • Block - The number assigned to the block.
  • Elapsed timer for the block - A timer that displays the elapsed time since the block creation.
  • To - The recipient address of the fee payment.
  • Value tZEN - The amount of TZEN transferred in the fee payment.

Blockchain Menu​

The Blockchain menu has these feature sections:

Transactions​

The Transactions section includes:

Validated Transactions​

Transaction validation indicates that a transaction conforms to a specific protocol requirement to deem it as valid. Once the transaction is considered valid, it is added to the distributed ledger.

The Validated Transaction feature provides key information about the transaction.

validated-transaction

Key information includes:

  • Txn hash - The unique identifier that validates the transaction.
  • Type - The specific type of the transaction (Coin transfer, Contract call, etc.).
  • Transaction Status - Indicates the status (Success or Error) details of the transaction.
  • Method - In the case of backward transfers the method is always backwardTransfer.
  • From - The sending address of the transaction.
  • To - In the case of backward transfers the destination address is the Withdrawal Request native contract.
  • Value tZEN - The amount of TZEN transferred in the transaction.
  • Fee tZEN - The TZEN amount charged to process the transaction.

Blocks​

The Blocks section includes:

  • All (all validated blocks)
  • Forked (forked blocks)

Forked blocks or chain reorganization takes place when a block is removed from the blockchain and a node receives blocks that are part of a new (longest) chain.

forks

Key information the validated and forked blocks includes:

  • Block - The number assigned to the block.
  • Elapsed timer for the block - A timer that displays the elapsed time since the block creation.
